The hypothalamus and the sympathetic nervous system are primarily associated with the general adaptation syndrome. The hypothalamus initiates the stress response, while the sympathetic nervous system activates fight-or-flight reactions in response to stress.
The majority of CNS stimulants are chemically similar to the neurohormone norepinephrine, and simulate the traditional "fight or flight" syndrome associated with sympathetic nervous system arousal.

The fight or flight response is primarily associated with the first stage of General Adaptation Syndrome (GAS), known as the alarm reaction stage. This initial response occurs when an individual perceives a threat, triggering the body's immediate physiological reactions, such as increased heart rate and adrenaline release. This prepares the body to either confront or flee from the danger. If the stressor persists, the body may move into the resistance stage, where it attempts to adapt to the ongoing stress.
Yes, glycogen synthesis is associated with the "fight or flight" reaction. During stressful situations, the body releases adrenaline, which activates signaling pathways that promote glycogen synthesis in the liver and muscles to provide energy for immediate use in response to the perceived threat.
Insulin is not typically referred to as the fight or flight hormone. This term is commonly associated with adrenaline, which is released during times of stress or danger to prepare the body for a fight or flight response. Insulin, on the other hand, is a hormone that regulates blood sugar levels by promoting the uptake of glucose into cells for energy or storage.
The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.
